Using Custom Permission Options¶
TYPO3 allows extension developers to register their own permission options, managed automatically by the built-in user group access lists. The options can be grouped in categories. A custom permission option is always a checkbox (on/off).
The scope of such options is the backend only.
Options are configured in the global variable
EXT:my_extension/ext_tables.php. The syntax is demonstrated in
the following example, which a custom permission option:
// Register some custom permission options shown in BE group access lists $GLOBALS['TYPO3_CONF_VARS']['BE']['customPermOptions']['tx_styleguide_custom'] = [ 'header' => 'Custom styleguide permissions', 'items' => [ 'key1' => [ 'Option 1', // Icon has been registered above 'tcarecords-tx_styleguide_forms-default', 'Description 1', ], 'key2' => [ 'Option 2', ], ], ];
The result is that these options appear in the group access lists like this:
As you can see it is possible to add both an icon and a description text. If icons not provided by the Core are used, they need to be registered with the Icon API.
To check if a custom permission option is set call the following API function from the user object:
$GLOBALS['BE_USER']->check('custom_options', $catKey . ':' . $itemKey);
$catKey is the category in which the option resides. From the example
above this would be
$itemKey is the key of the item in the category you are evaluating.
From the example above this could be
depending on which one of them you want to evaluate.
The function returns true if the option is set, otherwise false.
Keys for Options¶
It is good practice to use the extension keys prefixed with
the first level of the array to avoid potential conflicts with other
Never pick a key containing any of the characters ",:\|". They are reserved delimiter characters.
